Description

Technical Field

[0001] The present application belongs to the technical field of water purification equipment, and specifically relates to a water purifier. Background Art

[0002] In recent years, with the rapid development of China's economy, people's desire to improve the quality of life has become increasingly high. Water purifiers were born under this situation and have been widely used by people. With the increase in people's demand for use, higher requirements have been put forward for the displacement of water purifiers. Taking RO water purifiers as an example, a booster pump is usually used to pressurize tap water and pass it through the RO membrane to achieve the filtration and purification of tap water. If you want to increase the flow rate of purified water, you need to increase the power of the booster pump to increase the purification speed of tap water. The increase in the power of the booster pump is accompanied by greater vibration of the water purifier. The vibration of the water purifier body will also bring greater noise, which will disturb people when using it and affect the user experience.

[0003] In order to solve this technical problem, some water purifiers set the booster pump to consist of an outer shell and a pump body inside the outer shell, and set a vibration reduction structure between the outer shell and the pump body to weaken the relative collision caused by vibration during the operation of the pump body. However, such a setting makes the structure of the booster pump more complicated, and because it is necessary to reserve installation space for the vibration reduction structure, the volume of the booster pump is increased, which is not conducive to the miniaturization of the booster pump; on the other hand, setting a vibration reduction structure inside the booster pump can only weaken the vibration generated by the booster pump, but cannot completely eliminate it. The vibration generated by the booster pump will still cause relative collision between the booster pump and the water purifier body, so as to transmit the vibration to the body, and propagate outward through the body, and affect the other parts of the water purifier. Utility Model Content

[0004] The present application provides a water purifier to solve the technical problems that the booster pump of a traditional water purifier has a complex structure and a large volume in order to reduce noise, and the relative vibration between the booster pump and the water purifier body cannot be effectively reduced.

[0005] The technical solution adopted in this application is:

[0006] A water purifier comprises a frame, a filter unit arranged on the frame to filter water, and a booster pump arranged on the frame to pressurize the filter unit, the frame is provided with an installation cavity adapted to the booster pump, and the frame is provided with a positioning platform at the entrance of the installation cavity, the booster pump comprises a pump body and a pump head arranged at one end of the pump body, a vibration damping ring is provided outside the pump body, and two ends of the vibration damping ring are respectively abutted against the positioning platform and the pump head to limit the displacement of the vibration damping ring along the axial direction of the installation cavity.

[0007] The water purifier described in this application also includes the following additional technical features:

[0008] A plurality of positioning columns are disposed along the circumference of one side of the pump head. The positioning columns protrude and extend toward the pump body and abut against the vibration-damping ring.

[0009] The elastic center of the vibration damping ring coincides with the center of gravity of the boost pump.

[0010] The vibration-damping ring is interference-fitted with the pump body, and the vibration-damping ring is provided with a plurality of vibration-damping holes along its circumference.

[0011] The inner ring of the vibration damping ring is matched with the outer contour of the pump body, the outer ring of the vibration damping ring is polygonal, the positioning platform is provided with a flange portion extending toward the pump head, and the outer ring of the vibration damping ring abuts against the flange portion.

[0012] The water purifier further comprises a pressure plate mounted on the frame, wherein the pressure plate is located on a side of the pump head away from the pump body, and an elastic member is sandwiched between the pressure plate and the pump head.

[0013] A vibration-damping pad is sandwiched between the elastic member and the pump head. The vibration-damping pad includes a pad body and an outer flange connected to the pad body and extending toward one side of the elastic member. The outer flange cooperates with the pad body to form a receiving groove for receiving one end of the elastic member.

[0014] A mounting groove matched with the elastic member is provided on one side of the pressure plate facing the pump head, and one end of the elastic member is placed in the mounting groove.

[0015] A water-isolating gap is provided between the pump body and the inner wall of the installation cavity.

[0016] The pump body is placed in the installation cavity in a transverse direction, and the frame is provided with a drainage hole communicated with the installation cavity.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The water purifier of the present application is provided with a positioning platform for installing the booster pump at the entrance of the installation cavity, which is convenient for the assembler to install and position the booster pump during the assembly process. At the same time, a vibration-damping ring is provided outside the pump body. When the booster pump has a tendency to shift along the axial direction of the installation cavity due to vibration during operation, the positioning platform and the vibration-damping ring cooperate to limit the displacement of the vibration-damping ring along the axial direction of the installation cavity. On the one hand, the vibration amplitude of the booster pump itself is reduced, the vibration source is weakened, and the probability of the booster pump being displaced during the vibration displacement process is reduced. On the other hand, the transmission of vibration from the booster pump to the positioning platform is greatly weakened, and the vibration-damping effect on the booster pump is improved in many ways. In addition, since the vibration-damping ring is arranged on the outside of the booster pump, it will not occupy the space inside the booster pump, eliminating the installation space reserved in the booster pump for installing the vibration-damping ring, which helps to optimize the structural design of the booster pump and contributes to the miniaturization of the booster pump. In addition, the other end of the vibration damping ring abuts against the pump head, thereby ensuring the setting position of the vibration damping ring on the booster pump and preventing it from shifting, making the position of the vibration damping ring relative to the booster pump and the positioning table controllable, and ensuring the vibration damping effect.

[0019] 2. As a preferred embodiment of the present application, by setting up a plurality of positioning columns, when the pump head vibrates, the vibration is transmitted to the vibration damping ring through the plurality of positioning columns, thereby reducing the vibration energy borne by a single positioning column, and helping to reduce the possibility of stress concentration on the positioning column; and by setting up the positioning columns, the requirements for the size of the pump head and the vibration damping ring are reduced, and the vibration damping ring can be set to be shorter in the axial direction of the booster pump, and the positioning columns are used to compensate for the distance difference between the vibration damping ring and the pump head, thereby reducing the requirements for the size and structural form of the vibration damping ring, and helping to optimize the structural design of the vibration damping ring.

[0020] 3. As a preferred embodiment of the present application, since the pump head will not only generate vibrations along the axial direction of the booster pump when working, but also generate vibrations perpendicular to the axial direction of the booster pump or at a certain angle to the axial direction of the booster pump, the elastic center of the vibration damping ring is set to coincide with the center of gravity of the booster pump, so that the vibration damping ring will not be eccentric when bearing the vibrations from the pump head along the axial direction of the booster pump, and the vibrations from the pump head can be evenly absorbed by the vibration damping ring, avoiding the occurrence of the vibration damping ring deviation caused by uneven peripheral force; similarly, for the vibrations generated by the pump head at a certain angle to the axial direction of the booster pump, the vibration damping ring can also absorb them evenly, reducing the possibility of uneven absorption of the vibration of the pump head by the vibration damping ring due to the deviation of the elastic center of the vibration damping ring and the center of gravity of the booster pump, which helps to improve the vibration damping efficiency of the vibration damping ring. Moreover, such a setting can decouple the vibration of the booster pump in the six degrees of freedom directions, effectively reducing the vibration transmission of the booster pump to the frame.

[0021] 4. As a preferred embodiment of the present application, the vibration damping ring is set to have an interference fit with the pump body. On the one hand, it can improve the fit between the vibration damping ring and the pump body, thereby improving the vibration absorption effect of the vibration damping ring on the pump body; on the other hand, it saves the need to provide a mounting structure on the pump body for mounting the vibration damping ring, which helps to optimize the structural design of the pump body. Furthermore, the vibration damping ring is provided with a plurality of vibration damping holes in the circumference. When the vibration damping ring is partially deformed after absorbing vibration, it can provide a partial deformation margin for the vibration damping ring. The vibration force and torsional force absorbed by the vibration damping ring can be partially offset by its own deformation, thereby improving the vibration damping effect of the vibration damping ring and reducing the possibility of the vibration damping ring being crushed after absorbing a large amount of vibration force and torsional force.

[0022] 5. As a preferred embodiment of the present application, the inner ring of the vibration damping ring is configured to be compatible with the outer contour of the pump body, thereby improving the fit between the vibration damping ring and the pump body and avoiding the influence of the gap between the vibration damping ring and the pump body on the vibration absorption of the vibration damping ring, which helps to improve the vibration damping effect of the vibration damping ring; and because the outer ring of the vibration damping ring is polygonal and abuts against the flange portion of the positioning table, it can limit the rotation of the vibration damping ring in the axial direction of the installation cavity, thereby avoiding the influence of the vibration damping effect caused by the deviation of the vibration damping ring.

[0023] 6. As a preferred embodiment of the present application, when the booster pump generates vibrations along its axial direction during operation, the booster pump will inevitably be displaced along its axial direction, and a pressure plate and an elastic member are arranged between the pump head and the frame, so that the elastic member can buffer and absorb the vibrations of the booster pump along its axial direction, convert part of the vibration kinetic energy into elastic potential energy of the elastic member, and transmit it to the frame through the pressure plate, thereby weakening the transmission of vibration from the booster pump to the frame, and the vibration energy and elastic potential energy are dispersed through the pressure plate during the transmission process from the elastic member to the machine body, thereby reducing the kinetic energy transfer area between the elastic member and the machine body, so as to reduce the possibility of stress concentration between the elastic member and the machine body.

[0024] 7. As a preferred embodiment of the present application, a vibration-damping pad is arranged between the elastic member and the pump head, so that the vibration is reduced when the pump head is transmitted to the elastic member, thereby further reducing the vibration transmission from the booster pump to the body, which helps to reduce the vibration impact on the body; in addition, the accommodating groove formed by the pad body and the outer flange provides an installation and positioning space for the elastic member, eliminating the need to set a mounting structure for installing the elastic member at the pump head or other positions; that is, the vibration-damping pad integrates both the function of absorbing the vibration of the booster pump and the function of providing an installation space for the elastic member, the functions are further integrated, and the structural design of the vibration-damping pad is optimized.

[0047] like Figure 1As shown, a water purifier includes a frame 1, a filter unit arranged on the frame 1 to filter water, and a booster pump 2 arranged on the frame 1 to pressurize the filter unit, the frame 1 is provided with a mounting cavity 11 adapted to the booster pump 2, and the frame 1 is provided with a positioning platform 12 at the entrance of the mounting cavity 11, the booster pump 2 includes a pump body 21 and a pump head 22 arranged at one end of the pump body 21, a vibration-damping ring 3 is provided outside the pump body 21, and two ends of the vibration-damping ring 3 are respectively abutted against the positioning platform 12 and the pump head 22 to limit the displacement of the vibration-damping ring 3 along the axial direction of the mounting cavity 11.

[0048] The water purifier of the present application is provided with a positioning platform 12 for installing the booster pump 2 at the entrance of the installation cavity 11, which is convenient for the assembler to install and position the booster pump 2 during the assembly process. At the same time, a vibration-damping ring 3 is arranged outside the pump body 21. When the booster pump 2 has a tendency to shift along the axial direction of the installation cavity 11 due to vibration during operation, the positioning platform 12 cooperates with the vibration-damping ring 3 to limit the displacement of the vibration-damping ring 3 along the axial direction of the installation cavity 11. On the one hand, the vibration amplitude of the booster pump 2 itself is reduced, the vibration source is weakened, and the probability of the booster pump 2 being offset during the vibration displacement process is reduced. On the other hand, the transmission of vibration from the booster pump 2 to the positioning platform 12 is greatly weakened, and the vibration reduction effect of the booster pump 2 is improved in many ways. In addition, since the vibration-damping ring 3 is arranged outside the booster pump 2, it will not occupy the space inside the booster pump 2, eliminating the installation space reserved in the booster pump 2 for installing the vibration-damping ring 3, which helps to optimize the structural design of the booster pump 2 and help the miniaturization of the booster pump 2. In addition, the other end of the vibration-damping ring 3 abuts against the pump head 22, thereby ensuring the setting position of the vibration-damping ring 3 on the booster pump 2 and preventing it from shifting, making the position of the vibration-damping ring 3 relative to the booster pump 2 and the positioning platform 12 controllable, and ensuring the vibration reduction effect.

[0049] The present application does not limit the abutment method between the pump head 22 and the vibration damping ring 3, and any of the following embodiments may be adopted:

[0050] Embodiment 1: A first abutting surface is provided on the side of the pump head facing the vibration damping ring, and a second abutting surface matching the first abutting surface is provided on the side of the vibration damping ring facing the pump head. When the vibration damping ring abuts the pump head, the first abutting surface fits the second abutting surface.

[0051] Implementation method 2: Figure 1As shown, a plurality of positioning columns 221 are provided along the circumference of one side of the pump head 22, and the positioning columns 221 protrude and extend toward the pump body 21 and abut against the vibration damping ring 3. By providing a plurality of positioning columns 221, when the pump head 22 vibrates, the vibration is transmitted to the vibration damping ring 3 through the plurality of positioning columns 221, thereby reducing the vibration energy borne by a single positioning column 221, and helping to reduce the possibility of stress concentration on the positioning columns 221; and by providing the positioning columns 221, the requirements for the size of the pump head 22 and the vibration damping ring 3 are reduced, and the vibration damping ring 3 can be set to be shorter in the axial direction of the booster pump 2, and the positioning columns 221 are used to make up for the distance difference between the vibration damping ring 3 and the pump head 22, thereby reducing the requirements for the size and structural form of the vibration damping ring 3, and helping to optimize the structural design of the vibration damping ring 3.

[0052] As a preferred embodiment of the second embodiment, the pump head 22 includes a front cover and a base, the front cover is provided with a plurality of first positioning holes, the base is provided with a plurality of second positioning holes, and the second positioning holes extend through the positioning posts 221, and the front cover and the base are connected by fasteners passing through the first positioning holes and the second positioning holes. In this embodiment, the positioning posts 221 not only play a role in abutting against the vibration damping ring 3 to limit the displacement of the vibration damping ring, but also provide support for the connection between the front cover and the base of the pump head 22, achieving multiple uses.

[0053] As a preferred embodiment of the present application, the elastic center of the vibration damping ring 3 coincides with the center of gravity of the booster pump 2. Since the pump head 22 will not only generate vibrations along the axial direction of the booster pump 2 when working, but also generate vibrations perpendicular to the axial direction of the booster pump 2 or at a certain angle to the axial direction of the booster pump 2, the elastic center of the vibration damping ring 3 is set to coincide with the center of gravity of the booster pump 2, so that the vibration damping ring 3 will not be eccentric when bearing the vibration from the pump head 22 along the axial direction of the booster pump 2, and the vibration from the pump head 22 can be evenly absorbed by the vibration damping ring 3, avoiding the occurrence of the vibration damping ring 3 offset due to uneven peripheral force; similarly, the vibration generated by the pump head 22 at a certain angle to the axial direction of the booster pump 2 can also be evenly absorbed by the vibration damping ring 3, reducing the possibility of uneven absorption of the vibration of the pump head 22 by the vibration damping ring 3 due to the offset of the elastic center of the vibration damping ring 3 and the center of gravity of the booster pump 2, which helps to improve the vibration damping efficiency of the vibration damping ring 3. Moreover, such an arrangement can decouple the vibration of the booster pump 2 in the directions of six degrees of freedom, and effectively reduce the vibration transmission from the booster pump 2 to the frame 1.

[0054] As a preferred embodiment of the present application, the vibration damping ring 3 is interference fit with the pump body 21, and the vibration damping ring 3 is provided with a plurality of vibration damping holes 31 along its circumference. The vibration damping ring 3 is set to be interference fit with the pump body 21. On the one hand, it can improve the fit between the vibration damping ring 3 and the pump body 21, thereby improving the vibration absorption effect of the vibration damping ring 3 on the pump body 21; on the other hand, it saves the need to provide a mounting structure for mounting the vibration damping ring 3 on the pump body 21, which helps to optimize the structural design of the pump body 21. Furthermore, the vibration damping ring 3 is provided with a plurality of vibration damping holes 31 in the circumference. When the vibration damping ring 3 is partially deformed after absorbing vibration, it can provide partial deformation margin for the vibration damping ring 3. The vibration force and torsional force absorbed by the vibration damping ring 3 can be partially offset by its own deformation, thereby improving the vibration damping effect of the vibration damping ring 3, and at the same time reducing the possibility of the vibration damping ring 3 being crushed after absorbing a large amount of vibration force and torsional force.

[0055] Of course, the present application does not limit the connection method between the vibration damping ring 3 and the pump body 21. In another embodiment, a positioning protrusion is provided on the inner side of the vibration damping ring, and a positioning groove adapted to the positioning protrusion is provided on the pump body. When the positioning protrusion is buckled into the positioning groove, the inner wall of the vibration damping ring abuts against the outer wall of the pump body.

[0056] As a preferred implementation of the present application, Figure 2 , Figure 3 As shown, the inner ring of the vibration damping ring 3 is adapted to the outer contour of the pump body 21, the outer ring of the vibration damping ring 3 is polygonal, the positioning platform 12 is provided with a flange portion 121 extending in the direction of the pump head 22, and the outer ring of the vibration damping ring 3 abuts against the flange portion 121. The inner ring of the vibration damping ring 3 is arranged to be adapted to the outer contour of the pump body 21, which improves the degree of fit between the vibration damping ring 3 and the pump body 21, avoids the influence of the gap between the vibration damping ring 3 and the pump body 21 on the vibration absorption of the vibration damping ring 3, and helps to improve the vibration damping effect of the vibration damping ring 3; and because the outer ring of the vibration damping ring 3 is polygonal and abuts against the flange portion 121 of the positioning platform 12, it can limit the vibration damping ring 3 to limit the rotation of the vibration damping ring 3 around the axial direction of the installation cavity 11, thereby avoiding the influence of the vibration damping effect caused by the deviation of the vibration damping ring 3. In a specific example, the outer ring of the vibration damping ring 3 is square.

[0057] As a preferred implementation of the present application, Figure 1As shown, the water purifier also includes a pressing plate 4 installed on the frame 1, the pressing plate 4 is located on the side of the pump head 22 away from the pump body 21, and an elastic member 5 is sandwiched between the pressing plate 4 and the pump head 22. When the booster pump 2 generates vibration along its axial direction during operation, it is bound to cause the booster pump 2 to move along its axial direction, and the pressing plate 4 and the elastic member 5 are arranged between the pump head 22 and the frame 1, so that the elastic member 5 can buffer and absorb the vibration of the booster pump 2 along its axial direction, convert part of the vibration kinetic energy into elastic potential energy of the elastic member 5, and transmit it to the frame 1 through the pressing plate 4, thereby weakening the transmission of vibration from the booster pump 2 to the frame 1, and the vibration energy and elastic potential energy are dispersed through the pressing plate 4 during the transmission process from the elastic member 5 to the body, reducing the kinetic energy transmission area between the elastic member 5 and the body, so as to reduce the possibility of stress concentration between the elastic member 5 and the body.

[0058] The present embodiment does not limit the connection method between the pressing plate 4 and the frame 1. In one embodiment, the pressing plate 4 and the frame 1 are connected by bonding. If the pressing plate 4 and the frame 1 are both made of metal, welding can be used for connection. In another embodiment, the frame 1 is provided with a positioning groove for installing the pressing plate 4. The pressing plate 4 is snap-fitted into the positioning groove to achieve a detachable connection with the frame 1. In another embodiment, the frame 1 and the pressing plate 4 are fixed by screws.

[0059] The present embodiment does not limit the structural form of the elastic member 5 , and a spring may be used as the elastic member 5 , or rubber, or a soft plastic that can undergo elastic deformation, etc. may be used as the elastic member 5 .

[0060] As a preferred embodiment of this implementation, Figure 1 , Figure 4 , Figure 6 As shown, a vibration-damping pad 6 is sandwiched between the elastic member 5 and the pump head 22, and the vibration-damping pad 6 includes a pad body 61 and an outer flange 62 connected to the pad body 61 and extending toward one side of the elastic member 5, and the outer flange 62 cooperates with the pad body 61 to form a receiving groove 9 for accommodating one end of the elastic member 5. The vibration-damping pad 6 is arranged between the elastic member 5 and the pump head 22, so that the vibration is reduced when the pump head 22 is transmitted to the elastic member 5, thereby further reducing the vibration transmission from the booster pump 2 to the body, which helps to reduce the vibration impact on the body; in addition, the receiving groove 9 formed by the pad body 61 and the outer flange 62 provides an installation and positioning space for the elastic member 5, eliminating the need to set a mounting structure for installing the elastic member 5 at the pump head 22 or other positions; that is, the vibration-damping pad 6 integrates the function of absorbing the vibration of the booster pump 2 and the function of providing an installation space for the elastic member 5, and the function is further integrated, optimizing the structural design of the vibration-damping pad 6.

[0061] This embodiment does not limit the installation method of the elastic member 5, and it can adopt any one of the following embodiments:

[0062] Embodiment 1: A mounting groove adapted to the elastic member is provided on one side of the pump head facing the pressure plate, and one end of the elastic member 5 together with the shock absorbing pad 6 is placed in the mounting groove.

[0063] Embodiment 2: Figure 1 As shown, the side of the pressing plate 4 facing the pump head 22 is provided with a mounting groove 41 adapted to the elastic member 5, and one end of the elastic member 5 is placed in the mounting groove 41. With such a configuration, the pressing plate 4, on the basis of assuming the function of evenly distributing the vibration energy and elastic potential energy on the elastic member 5, further integrates the function of installing the elastic member 5, and the function is further integrated. Compared with the first embodiment, it is possible to avoid providing an assembly groove for installing the elastic member 5 on the pump head 22, which helps to optimize the structural design of the pump head 22 and reduce the difficulty of producing the pump head 22.

[0064] As a preferred implementation of the present application, Figure 5 As shown, there is a water-proof gap 7 between the pump body 21 and the inner wall of the installation cavity 11. When water seepage occurs in the waterway interfaces of the booster pump 2, the water-proof gap 7 provides a clearing channel for the seeping water flow, thereby preventing the seeping water from affecting other components of the water purifier.

[0065] As a preferred embodiment of this implementation, Figure 5 As shown, the pump body 21 is placed in the installation cavity 11 in a horizontal direction, and the frame 1 is provided with a drainage hole 8 connected to the installation cavity 11. With such a configuration, when installing the pump body 21, the assembler can place one end of the pump body 21 in the installation cavity 11 and then push the pump body 21 to slide and enter the installation cavity 11, so that the installation cavity 11 can guide the installation of the pump body 21. Compared with installing the pump body 21 vertically or in other directions, pushing the pump body 21 into the installation cavity 11 in a horizontal direction can reduce the force applied by the assembler when supporting or lifting the pump body 21, reduce the assembly difficulty of the assembler, and help improve the installation efficiency of the pump body 21; in addition, by providing the drainage hole 8, when the booster pump 2 leaks and the water-isolating gap 7 cannot completely block the water flow, the water flow entering the installation cavity 11 will be discharged from the frame 1 under the guidance of the drainage hole 8, further reducing the possibility of the water flow affecting the other components of the water purifier.
